Authors have studied on the synthesis of new type of chelate surfactants having very good dispersing power for TiO<SUB>2</SUB> in organic solvents. Within these chelates. C, C'-bisdecyl EDTA Al chelate (BDe), C-decyl, C'-dodecyl EDTA Al chelate (DeDo) and C, C'-bisdodecyl EDTA Al chelate (BDo) were added to the aminoalkyd resin enamels for improvement the properties of coating films. These coating films were tested on the chemical resistance (acid, alkali and detergent) and were measured for Dupon impact resistance, gloss and bending resistance after weathering. It was found that these surfactants improved much the chemical resistance, namely, softening of the coating films containing some of the dispersants did not take place even after immersing in 2% NaOH or 0.2% detergent solution for 3 days. Also, these dispersants effectively prevented the gloss drop and the embrittling of coating films under weathering.
